Answer: (C)

Verified step by step guidance

1. Understand the definition of a solution: A solution is a homogeneous mixture of two or more substances, meaning the composition is uniform throughout.
2. Recognize the roles of solute and solvent: The solute is the substance dissolved, and the solvent is the substance doing the dissolving. The solvent is usually present in a greater amount than the solute, but this is not always the case.
3. Note that solutions are not limited to water as the solvent; many solvents other than water can form solutions, such as alcohols, acetone, and liquid metals.
4. Understand that solutions can exist in different phases: solids dissolved in liquids, gases dissolved in liquids, liquids dissolved in liquids, and even solids dissolved in solids.
5. Conclude that the correct statement is that a solution is a homogeneous mixture of two or more substances, as this definition encompasses all types of solutions regardless of the physical states of solute and solvent.
